Harry Potter and the Methods of Rationality discussion thread, March 2015, chapter 114 + chapter 115

Gondolinian

This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 114, and also, as a special case due to the exceptionally close posting times, chapter 115.

There is a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)

Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:

You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).

If there is evidence for X in MOR and/or canon then it’s fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that “Eliezer said X is true” unless you use rot13.

That assumes a great deal of control over the design of the network. We don't know what steps Voldemort followed to design the Horcrux 2.0 ritual, but I don't think it implausible that the final result was the best he could do with the knowledge available, rather than the best an intelligent programmer could do with full control over the system's hardware and code.

I agree.

Also, the added complexity of distributed computations (Username’s suggestion) versus distributed real-time backups (the Horcrux 2.0) is enormous! Even for teams of extremely smart developers in 2015, distributed computing is not a simple problem. For one single “developer” in ~1990, like Voldemort (who has no like-minded individuals to discuss this with and has absolutely no background in computer science), this is near-impossible unless Magic has a built-in API that makes this extremely easy (which is unlikely, given what we know about the APIs for horcruxes, ghosts, etc.)
